[okl4-developer] Problem running wombat (unknown syscall)

[Carl van Schaik]

What is happening is that your default toolchain is NPTL enabled. You
need to use a separate toolchain. Sometimes, the Linux distribution you
are using has both versions of the libraries, one in /libs/tls/... 
hence the previous mail to move this directory out of the way so the
non-NPTL libraries can be found.

However, you may want to build you on non-NPTL toolchain (using
crosstool), or download one.
You need to specify the toolchain to use on the command line and ensure
it is in your current PATH.
to specify the toolchain, use    "toolprefix=i686-pc-linux-gnu-"   or
whatever the toolchain prefix is. Note this must be different to any
other toolchain on your system or you have to be really careful about
your PATH.

one preecompiled one can be found at:
